The food, water, and other essentials in your More Prepared survival kit have a shelf life of up to five years. Each kit is marked with a “Best By” date so you’ll always know when items are nearing expiration. When it’s time to refresh your supplies, we’ll send you a reminder email, and you can easily replace everything with one of our replenishment kits. Available in 1-, 2-, and 4-person sizes, these kits are an economical way to keep your emergency supplies current without replacing the entire kit.
